Study Notes
Volume of a Regular Solid
- Volume is the amount of space an object occupies.
- Volume of a regular solid is obtained by multiplying its length, width, and thickness.
- Volume is expressed in cubic units (e.g. cubic meter, cubic cm).
Volume of a Liquid
- Liquid volume is measured in cubic meters or liters (L).
- Graduated cylinder is used to measure the volume of a liquid.
- When reading the measurement of a clear liquid, read the lower meniscus.
- When reading the measurement of a colored liquid, read the upper meniscus.
- 1 dm³ = 1 liter (L) and 1 cm³ = 1 milliliter (mL).
Volume of an Irregular Solid
- An irregular solid is one where a dimension cannot be measured in a single straight line.
- The displacement method is used to determine the volume of irregular solids.
- The displacement method involves filling a container with water, putting the object in the container, and catching the overflow to get the volume of the overflow.
Density
- Density is the mass of an object per unit volume.
- Substances differ in their densities, and each substance has a specific density.
- Density is calculated using the formula: D = Mass / Volume (g/cc).
- Materials with a density less than 1 g/cc (density of water) will float on water, and those with a density greater than 1 g/cc will sink.
